SE LF-LOADING CART.

To all whom it may concern.-

Be it known that 1, ROBERT CHARLES MEN- miss, a citizen of the UnitedStates, residing at Glens Falls, in the county of Warren and State ofNew York, have invented a new and useful Self-Loading Cart, of which thefollowing is a specification.

This invention relates to street cleaning devices; and it has among itsobjects to provide a device of this class which shall be simple inconstruction, durable, and efficient in operation.

Among the special objects of the invention are the production of anorganized machine in which means for gathering and collecting the dirtor refuse shall be mounted upon a wheel-supported frame in connectionwith a receptacle into which the refuse may be emptied from time totime, said wheel-supported frame affording also a seat for an operator,who by pedaling causes the machine to be propelled over the ground andsupplies the motive power needed for the operation of movable members ofthe device.

A further object of the invention is to provide an improveddirt-receiver and means for elevating the same, so as to cause it to beemptied into the receptacle which is carried by the machine.

Patented Jan. 23, 1906.

In said drawings, Figure 1 is a perspective view of a street-cleaningdevice constructed in accordance with the principles of the invention.Fig. 2 is a side elevation of the same. Fig. 3 is a rear elevation. Fig.4 is a detail top plan view.

Corresponding parts in the several figures are indicated by similarnumerals of reference.

The frame of this improved machine in chides a tubular bearing 1, inwhich is journaled the front fork 2, affording bearings for the axle ofa light wheel 3, which is preferably rubber-tired and of ordinarybicycle construction. The upper end of the front fork carries ahandle-bar 4, by means of which the machine may be steered, as will bereadily understood.

Extending rearwardly from the tubular bearing 1 are the side frame-bars5 and 6, whichfor the sake of combining lightness and strength arepreferably of tubular construction. The side bar 5, which I term theinner side bar, is approximately straight and is extended in a rearwarddirection, terminating at its rear end in downwardly-extending forkmembers 7 and 8, having bearings for the spindle 9 of the rear wheel 10,which is disposed approximately in the same vertical plane as the frontor guiding wheel 3.

The outer side bar 6 is provided with offset portions or curves wherebyits rear end is considerably spaced apart from the rear end of the innerside bar 5. The rear end of said outer side bar is provided withdownwardlyextending fork members 11 and 12, affording bearings for thespindle 13, carrying the rear supporting-wheel 14, which is in axialalinement with the rear supporting-wheel 10, the spindles 9 and 13 beingconnected by means of a shaft 15. A cross-bar 16 connects the upper endsof the fork members 7 S and 11 12, and suitably-disposed brace membersare to be employed for the purpose of strengthening the frame structurewherever needed. The inner side bar 5 also supports a seat 17 and adownwardly-extending arm or bracket 18, provided at its lower end with abearing for a crank-shaft 19, the cranks of which are provided withpedals 20. The crank-shaft 19 carries a sprocket-wheel 21, connected bya chain 22 with a sprocket-wheel 23 upon the hub of the driving-wheel10, to which motion may thus be transmitted, as will be readilyunderstood.

The inner and outer side bars 5 and 6 of the frame are connected neartheir rear ends by a cross-bar 24, provided with upturned ends 25, whichrest and are supported upon the upper sides of the side bars and areconnected with the latter by means of verticallydisposed bolts or in anyother suitable and convenient manner. Suitably connected with andsupported by the cross-bar 24 are a pair of downwardly-extending strapsor hangers 26, terminating at their lower ends in approximatelyhorizontal supports or stirrups 27, having offsets 28 and. provided withupturned rear ends 29. These hangers are preferably constructed of flatstraps of metal of suitable dimensions, and the upturned portions of therear ends 29 of the stirrups are connected by a cross-bar 30, which maybe secured by means of bolts or rivets and the ends of which are bentupwardly, so as to form the arms 31 of a yoke of which the member 30 isthe cross-bar. The arms 31 are bent in a vertical plane, as will beclearly seen in Fig. 2 of the drawings, so that they may be described asextending upwardly and forwardly from the points at which they areconnected with the front ends of the stirrups 27 and thence upwardly tothe side bars 5 6 of the frame with which they are connected and wherebythey are firmly supported.

The cage or structure, comprising the hangers 26, stirrups 27, cross-bar30, and arms 31, is for the purpose of supporting the dust-receiver 32,which consists of a suitablyconstructed approximately rectangular box,which may be appropriately made of galvanized iron or other sheet metalsuitably protected against corrosion. The bottom 33 of this receiver isrounded at its front and rear portions, the rear portion. of said bottombeing extended beyond the box, so as to form a lip 34, appearing indotted lines in Fig. 2, and which when the receiver is in operativeposition is supported upon the cross-bar 30. The rear side of the box 32is entirely open for the reception of sweepings. The end pieces 35 ofthe box increase in height in the direction of their front portions, andthey ser ve to support a lid 36, which is hinged between the up per rearcorners of the end pieces. The rear edge of the lid or the rod whichhingedly supports said lid is provided with a guard-strip 37 of rubber,felt, or other suitable material, which when the receiver 32 is inoperative position abuts upon the front side of the brushcasing, whichwill be hereinafter described, said strip performing the double functionof steadying the receiver 32, so as to prevent rattling and ofpreventing the escape of dust upwardly in front of the brush-casingbetween the latter and the receiver 32.

38 designates the brush-casing, which is in the nature of a curved,partly cylindrical shield, having end pieces 39 and containing acylindrical rotary brush 40, which is mounted upon a shaft or axle 41,the ends of which project through segmental slots 42 in the ends of thecasing. The brush carrying shaft 41 is journaled in a pair ofrocker-arms 43, the opposite ends of which are pivotally mounted uponthe shaft 15, with which the slots 42 are concentric. The brush-casingis connected with the shaft 15 by means of clips, as best seen at 44, inFig. 1 of the draw ings. Additional supporting means for thebrush-casing are in the nature of chains 45, which connect said casingwith hooks 46 upon the frame of the machine.

The dust-receiver 32 is provided near the ends thereof with reinforcingstraps or bands 47, which coincide with the supporting-hangers 26 andwhich may be described as forming shoes engaging said hangers when thereceiver 32 is slid or moved upwardly for the purpose of discharging itscontents into a receptacle provided for the purpose or when it is moveddownwardly into its normal position upon the stirrups 27. The upward anddownward movement of the receiver 32 is effected by means of a yoke 48,the ends of the arms of which have pivotal connection with pins 49,extending from the ends of the receiver. The arms of the yoke, at thepoint where they meet each other, are quartertwisted and cooperate toform an arm 50.

51 designates a shaft which is journaled in bearings upon a portion ofthe outer side bar 6 of the frame, said portion of the side bar beingdisposed approximately parallel to the shaft 15. The ends of the shaft51 are bent at angles to the body of the shaft, thus forming arms 52,which converge at 53, so as to form the side members of an approximatelytriangular frame, of which the shaft 51 is the base. From the apex 53 ofthis frame the arms or side members 52 are extended in the direction ofthe arm of the yoke 48, with which they are pivotally connected, asindicated at 54.

Rigidly connected with the triangular frame, of which the rock-shaft 51is the base, is an operating-lever 55, having a pivoted handle member56, which is connected, by means of a rod or member 57, with one arm abell-crank 58, fulcrumed upon the extended ends of the side pieces 52.The free end of the bell-crank 58 terminates in a hook or ratchet member59, which when the dust-receiver 32 is in a lowered or operativeposition, as shown in Fig. 2, automatically engages under the crossbar24, thus positively preventing displacement in an upward direction ofthe dust-receiver 32 and related parts. When the dust-receiver is inthis position, the operating-lever will be elevated, as best seen inFig. 2, to a convenient position accessible to the operator who occupiesthe seat 17. When it shall be desired to elevate the dust-receiver tothe position shown in Fig. 1, the operator grasps the handle portion ofthe lever 55, thus actuating the pivoted grip portion 56, and throughthe latter and the rod 57 the bell-crank 58, having the catch 59, whichis thus released from the cross-bar 24, thereby permitting the lever 55to be moved in a downward direction, so as to elevate the dust-receiver,as will be readily understood.

For the purpose of assisting in raising the weight of the dust-receivera spring 60 is provided, a portion of said spring being wound upon theshaft 51, so as to form two coils or helices and a central dependingtongue 61, which is inserted under the portion of the frame -bar 6 uponwhich the shaft 51 is mounted. The ends of the spring 60 are suitablyextended and connected with the apex 53 of the approximately triangularframe formed by the shaft 51 and side members 52. It is obvious that thetension of this spring will be exerted to assist in overcoming theweight of the receiver 32 when the latter is to be elevated. At the sametime it is not intended that the tension of this spring should besufliciently great to prevent the weight of the receiver from restoringit by gravity to its normal operative position.

The bearings in which the shaft 51 is mounted upon the frame-bar 6 arein the nature of blocks 62, each having an upper and a lower concaveside, engaging, respectively, the frame member 6 and the shaft 51, forwhich latter the said blocks form half-boxes. The boxes or bearings arecompleted by means of clips 63, which include between them the shaft 51,the blocks 62, and the frame member 6, all of which are thus firmlyunited, but in such a manner as to permit the shaft 51 to rock freely inits bearings in the manner and for the purposes herein indicated Thehangers 26, which, as hereinbefore described, are supported at theirupper ends upon the cross-bar 24, are extended in front of saidcrossbar, so as to form arms or brackets 64, through which extends arock-shaft 65,

- provided at the ends thereof with rearwardlyextending crank-arms 66,having hooks 67 at the extremities thereof. These hooks are normallyforced in a downward and a rearward direction by the action of springs68, suitably wound upon the rock-shaft and having their ends in contact,respectively, with the fixed bearings 64 and with the movable hookmembers, as will be readily understood. Upon the ends of thedust-receiver 32 are provided laterally extending pins 69, which whenthe dust-receiver is elevated by the means herein described will contactwith the hooks 67, whereby the hooks will be tilted upwardly as thedust-receiver continues its upward movement, while at the same time thesaid dust-receiver by the action of said hooks will be tilted upon itspivots to the position indicated in Fig. 1 of the drawings, by referenceto which it will be seen that the open rear side of said receiver isuppermost, while the lid 36 will swing open and cause the contents ofthe receiver to dump into a receptacle provided therefor. When thereceiver is lowered,,the hook members 67 will be caused by the tensionof the springs 68 to be automatically restored to their normal position,causing the dust-receiver likewise to be tilted into its normal positionwhile in the act of being lowered. Then it nearly reaches its lowermostlimit, the box will be pressed in a rearward direction by the shouldersor offsets 28 upon the hangers, thus forcing it to occupy the preciseposition with relation to the refuse-gathering mechanism which it isintended that it shall occupy.

The refuse-receptacle may be and is preferably in the nature of a can70, of galvanized iron or other suitable material, which is supportedupon hangers or bracket members 71, depending from the frame of themachine and which, each of said brackets being suitably located andconnected with the remaining ones, cooperate to form a convenientsupport for the can 70, which latter, however, may be readily removed bysimply lifting or tilting it off the support afforded by said brackets.Two of the latter are connected by means of a chain 72, which ispermanently connected to either of said brackets and detachablyconnected with the other, for instance, by means of a hook and staple 73and 74. This chain is simply for the purpose of retaining therefuse-receptacle securely in position during the operation of themachine and in such a manner that when it has become filled it may bequickly and conveniently removed and an empty one substituted in itsplace. It is obvious that any other well-known and approved means may beused for the purpose of detachably supporting the refuse-receptacle inits proper position. The latter is also preferably provided withhandles, as 74, by means of which it may be conveniently manipulated.

For the purpose of directing the refuse from the receiver 32 into thereceptacle I avail myself of a pair of hopper-shaped chutes 75, whichare mounted in and suitably connected with loops 76, formed upon asupport ing-rod 77, the rcarwardly-extending ends of which are suitablyconnected with the crossbar 24, said ends being arched so as not tointerfere with the rock-shaft 65 or related parts. The front portion ofthe supportingrod 77 is adapted to rest upon one or both of theclip-plates 78 of the clips 63, hereinbefore described. By these hoppersor chutes, which are disposed transversely with relation to the machineand the upper edges of which are spaced sufliciently apart to receivethe material discharged from the receiving-box 32 when the latter iselevated and tilted, as hereinbefore described, the refuse will bedirected into the receptacle placed underneath without the least dangerof spilling any portion thereof. The rearward-extending ends of thesupporting-rods 77 are coiled upon or otherwise hingedly connected withthe crossbar 24, so that when it shall be desired to remove the can orreceptacle from its supports the hopper-carrying frame may be swung backto a position indicated in. dotted lines in Fig. 2 of the drawings.

When it shall be desired in place of the metal can to use an ordinarygunny sack as a receptacle for the refuse collected by the machine, Iprefer to avail myself of a bagsupporting ring 79, (shown in Fig. 4 ofthe drawings,) said ring being provided with a hook member 80, adaptedto engage the cross-bar 24, the opposite side of the said ring beingpermitted to rest upon one or both of the clip-plates 78. Thisbag-supporting ring will be preferably provided with hooks, as 81, orother convenient and approved means whereby a bag may be supported inposition and which will permit such bag to e conveniently applied orremoved, as may be desired.

It has already been stated that by the use of this machine refuse isgathered by the cylindrical brush 40, which is mounted upon the shaft41, journaled in the free ends of arms or levers 43, fulcrumed upon theshaft 15. Rotary motion is conveyed to said brush from the driven rearwheel 10 of the machine. The mode of and means for transmitting motionand of throwing the cylindrical brush into or out of gear, as required,are as follows: The wheels 10 and 14 are both mounted to rotate freelyupon their respective spindles. The hub of the wheel 10 carries thesprocket-wheel 23, whereby it is connected, through the chain 22, withthe directly-driven sprocket 21. The hubs of each of the wheels 10 and14 carry disks 82, which are perforated for the reception of pins 83,extending from the hubs of gear-wheels 84, which are journaled upon theshaft 15 adjacent to the inner sides of the transportingwheels. Theinner ends of the hubs of the gear-wheels 84 are annularly grooved andare engaged by the bifurcated ends of levers 85, which are fulcrumed at86 upon the frame members 8 and 12 of the frame. It is obvious that bymoving the lovers in the proper direction. the gear-wheels may be movedaxially upon the shaft 15, causing the projecting pins 83 to pass intoor out of engagement with the perforations in the disks 82, therebylocking the gear-wheels upon or unlocking them from the hubs of thetransporting-wheels 10 and 14, as may be required. For the purpose ofactuating the levers 85 additional short levers 87 are provided, saidshort levers being fulcrumed upon the frame membersS and 12 below thefulcra of the levers 85, with which the outer ends of the levers 87 areconnected by means of links 88. The inner free ends of the levers 87 arepivotally connected with the lower ends of a pair of resilientoperating-rods 89, which, for the purpose of inducing resiliency in thedesired direction, are provided with loops 89 formed thereon. The rearcrossbar 16 of the frame of the machine is provided with brackets 90,with which are pivotally connected the approximately horizontal arms 91of a pair of bell-crank levers 92, the approximately vertical and longerarms 93 of which are connected with each other by a connecting-rod 94,said connecting-rod and levers cooperating to constitute a yoke.Pivotally connected with the cross-bar 94 is a forwardly-extendingconnecting-rod 95, the extended front end of which is connectedpivotally with a lever 96, which is fulcrumed upon the inner side of theside bar 5 of the frame at the point indicated by 97 and which isprovided with a crank or handle 98, by means of which it may be easilyreached and manipulated by the operator, the lever 96 being disposed, aswill be seen, in a convenient position between the drivers seat and thehandle-bar of the device. The rod 95, near its point of connection withthe lever 96, is slightly bent, as will be clearly seen in Fig. 2, sothat by depressing the front end of the lever 96 the pivotalconnecting-point of said lever and the connecting-rod will be thrownslightly past a dead-center, whereby the said connecting-rod and theparts oper ated thereby will be automatically retained in adjustedposition. The rear ends of the horizontal arms of the bell-erank levers92 are connected, by means of rods 99, with the arms 43, carrying therotary brush member of the device. Said arms are connected, by means ofchains 100, with the flanged edges of a conve'yer 101, which is in thenature of a pan provided with forwardly-extending ears or lugs 102,which are pivotally connected with the lower ends of the brackets 31,which in part support the dust-receiver, the front edge of theconveyer-pan 101 being normally supported upon the rearwardly-projectinglip 34 of the receiving-box 32, into which refuse will thus be guidedover the said pan or conveyor, as will be readily understood. Securedtransversely of the under sides of the stirrups 27, upon which thedust-receiveris practically supported, is a transverse bar 103, to whichis secured the front edge of a plate 104 of resilient material, such assheet-steel, said plate projecting under the conveyer-pan 101, the freeend of which is partially supported upon said resilient plate. The underside of the conveyer-pan is reinforced by a transversely-disposedcross-bar 105, which, in the drawings has been shown as being L- shapedfor the purpose of increasing the stiffness and rigidity of the pan. Itwill be seen that by operating the lever 96 in one direction, which isindicated by an arrow in Fig. 2 of the drawings, the bell-erank levers92 will be rocked upon their fulcra, with the re- ITO sult that theresilient connecting-bars 89 will be depressed, thus causing the levers87, through the links 88, to actuate the levers 85, thereby sliding thespur-wheels 84 outwardly upon the shaft upon which they are journaledandcausing them, by means of the pins 83 and disks 82, to becomeinterlocked with the transporting-wheels 10 and 14, thus causing them totransmit motion to the rotary brush 40, the shaft of which is providedat the ends thereof with spur-wheels 106, intermeshing with thegear-wheels 84. At the same time the rotary brush member, which iscarried by the arms 43, connected, b the rods 9.9 with the rear ends ofthe bell-crank levers 92, will be lowered into active or operativeposition in contact with the ground. Furthermore, and by the sameoperation, the free edge of the conveyer-pan, which is connected by thechain 100 with the link-bars 43, will be lowered for the purpose ofreceiving the refuse swept over it by the rotary action of the brush andguiding the same into the receiver 32.

The shaft 41, carrying the rotary brush member, is incidentally providedwith a compensating gearing, (conventionally indicated in dotted linesat 107 in Fig. 3 of the drawings,) the object of this being simply topermit the machine to turn freely in any direction, as will be readilyunderstood. This is an important feature of the device, for the reasonthat when the machine is thrown into operation both of thetransporting-wheels 10 and 14 will become interlocked with thebrush-operating mechanism, and without the presence of compensatinggearing the machine would be prevented from turning freely, which in adevice of this class is of the greatest importance, as will be readilyunderstood.

For the purpose of preventing the free end of the conveyer-pan 101 frombeing lowered too far, or rather for the purpose of controlling andregulating the exact point to which it may be lowered, I provide a pairof rods 108, pivot'ally connected with the flanges at the edges of saidpan and extending upwardly through a frame-bar or, if preferred, throughlugs or brackets connected with said frame-bar and provided at theirupper ends with regulating-nuts 109. It is obvious that the chains 100should be of sufficient length to permit the free edge of theconveyer-pan to be lowered as far as shall be necessary under anycircumstances; but by means of the connecting-rods 108 the free edge ofsaid pan may be sustained a short distance above the ground. This is forthe purpose of preventing it from acting as a scraper, whereby the dirtand refuse will be carried in front of the brush. The resilient shield104, which in part supports the conveyer pan 101, also performs animportant function in so sliding over the refuse and carrying the freeedge of the conveyer-pan over the same as to insure its being operatedupon directly by the brush member, whereby it is caused to pass over theconveyer-pan and into the receiver 32.

From the foregoing description, taken in connection with the drawingshereto anneXed, the nature of the invention and the operation andadvantages of the same will be readily understood by those skilled inthe art to which it appertains. The rotary brush member of which I availmyself for the purpose of gathering the refuse is not per se a part ofmy invention, rotary brush members having for a long time been wellknown for the purpose of gathering and collecting refuse. The inventionresides more particularly in the means for receiving the refuse, as itis being gathered or collected, in the mechanism for elevating thereceiver and for dumping or discharging its contents into a largerreceptacle carried and supported by the frame of the same organizedmachine of which the receiving and gathering devices form a part, and,further, in so mounting the several devices upon a wheel supported frameprovided with pedally-operated propulsion means that the entire machinemay be propelled over the ground and operated successfully to gather therefuse by an operator seated upon the machine, the principal I andgeneral object of the invention being to furnish a simple andconveniently-operable organized machine whereby the gathering of refuseshall be greatly facilitated and whereby it may be effected in a simple,convenient, and inexpensive manner.

In the operation of the machine the operator occupying the seat 17 mayride easily and swiftly from a central point or depot to the point whereoperations are to take place. While the machine is thus beingtransported the operative parts are held elevated in the positionillustrated in Fig. 2 and being of a comparatively light nature will notto any serious extent hamper the progress of the operator. As soon asthe place of operation is reached the operator, by means of the lever96, will throw the rotary gathering member 40 into contact with theground, simultaneously lowering the conveyer-pan 101'to its properposition and throwing the operating mechanism for the rotary brushmember into gear, as has been already described. It is here to beobserved that the throwing into gear of the rotary brush is effected inan eX- tremely simple manner, the driving mechanism being of thesimplest possible nature in order to avoid any of the parts being chokedby dirt. I have consequently avoided the use of complicated clutchdevices, which would be easily choked and rendered temporarily useless.Another important feature is the use of the vertically-resilientconnecting-rods 89 with the loops 89 whereby the parts directly operatedthereby will beretained in their desired relative positions with theutmost security, while the rigidity where by they would be exposed tobreakage even by slight jarring or jolting of the machine is entirelyabsent. As the machine progresses the refuse will be caused to pass overthe con- Veyer-pan 101 into the box or receiver 32 over the lip 34 atthe front edge of said box, upon which the rear edge of the pan 101normally rests. When a quantity of refuse has accumulated in thereceiver 32, the machine is stopped. The operator then, by means of thelever 55, elevates the dust-receiver 32, which as soon as it comes underthe influence of the upward pull upon the arms of the yoke 48 will slideforwardly upon the offset portions 28 of the supporting-bars 26, therebyenabling the lip 34 to pass out of engagement with the rear end of theconveyer-pan 101. The dust-receiver will then swiftly be elevated in themanner which has been already described until the pins 69, coming intoengagement with the hooks 67, will cause the receiver to be tilted untilthe lid 36 swings open and the contents of the box is dumped upon thehoppers or chutes 75, whereby it is discharged into the can or into suchmeans as have been provided for the reception thereof. By operating thelever 55 in a reverse direction the dust-receiver will be lowered andwhen it approaches the lower limit of its movement will be pushed by theshoulders or offsets 28 in a rearward direction,

thereby causing the lip 34 to pass under the rear edge of theconveyer-pan 101. In this lowered position the receiver 32 will besecurely maintained by the action of the hooks 59 upon the levers 58,operated by means of the connecting-rods 57 and hand-grips 56, said hookmembers engaging under the crossbar 24, as hereinbefore described. Thisdumping mechanism may be operated, if desired, without necessity ofthrowing the gathering mechanism and the means for transmitting motionout of gear. When the can or receptacle 7 O or the means for receivingthe refuse is full, it may be dumped easily and quickly detached and anempty one substituted in place thereof.
